1967 to 1968 production Mustangs with 427 Engine installation.

[sw44ma@yahoo.com]

I am interested in finding information. About the production use of the 427 engine in 1967 1968 Mustang production. I would like to know how many Mustangs were created with the 427 during that time.

Heck of a first question.

And asked on a Shelby site

How does ZERO sound? There were no 67-8 Mustangs, only a few 68 Cougars with the W code 427s. There are no Mustangs according to Kevin Marti for either year, despite it being shown as an option.

The mistery of the W Code, if somebody will find one that will maybe a million dollar baby ;-) maybe somewhere in mexico its sitting and waiting for bj or mecum  kevin marti will verify it

Marti has said that there are no 68 W code Mustangs in the Ford records. Only Cougars.

I don't remember what he said about '67s but there are only three 67 GT500's and those were all done after the fact by Shelby.

One is the Supersnake and it is a million dollar car several times over.


If you want a 67 427 then you are limited to R code Fairlanes or a 427 Cobra.

Here's everything that you need to know about factory installed 427 Mustangs in 1967 - 68:



That's everything.

The factory may not have created any, but the need for street and track dominance created its own niche,

About 14 years ago or so, I saw a 1968 W code Mustang GT fastback at the Tasca Ford car show. White with a red interior. It had the W on the windshield vin tag and a few bolt ons as I recall. Of course there was no Marti report or other paperwork to go with it. The point? Watch out for fakes because there are plenty of them out there. Like A Boss 302 with air conditioning, not a single documented one found ever.

[shelbydoug]

There are some good fakes out there.

Since Marti has the original Ford records, you need to consult with him.

Years ago I heard from John Paradise that he had seen several W code Mustangs and Cougars. I don't know what that's worth but it seems that W Mustangs are a fairy tale.

It just takes someone in a non-title state with a set of matching die stamps to make one.



I will add also, that the value of a W code engine is limited. It is essentially a 390 GT with a 427 block. Ford made a decision that the 428cj was a better combination.

If you say it's not a good racing engine, I would refer you to the results of the '68 NHRA Winter Nationals. Those results would indicate otherwise.

Wasn't Jimmys a W code ? Could be, maybe in Mejico...

As a side note, don't necessarily trust Marti reports or window stickers either. I've seen them faked as well. If you find a truly oddball car with a Marti report, order your own deluxe Marti report. The money may be well spent! If you want to find a truly rare car, try the 68 1/2 Montego/ Comet R code sedan. Total number built? 1!

Wow really bad information regarding 1968 W code 427 engines.

The 1968 W code 427 is a side oiler 427. It is unlike a 390 in nearly every respect except that the 427 shares a cast crankshaft with the 390.

The cylinder heads in the 427 for 1968 are the C8AE 6090-J head. Valve sizes and port design are the same as 428CJ and 427 Low Riser.

The intake on the 1968 W code 427 is shared with the W code 1967 Fairlane 427 and also with 1967 and early 1968 428 PI engines. It was also used, along with the cylinder heads on the 135 series 428CJ cars.

Connecting rods are the 13/32" type used in the 428CJ.

The 428CJ is a cheaper way to achieve the same cubic inches. The side oiler 427 was a costly and time consuming engine to build. It was necessary for Ford to build enough of them to homologate the 427 for competition in NASCAR and NHRA.

The 1968 427 is rated at 390 horsepower, which is higher than the Boss 429 that was used the following year to homologate that engine.

There likely would have been a lot more 427's built in 1968 model year had it not been for the strike. Ford and Mercury had planned to offer the 427 in a variety of models including the Mustang and Shelby. It never happened of course.

The 428CJ was under development at the time, and was rushed into production at midyear due to the lack of performance engines to use in other product lines.

There are some good fakes out there.

A couple of years ago I heard firsthand from Kevin at the Cougar nationals on his trek to Mexico to see the 2nd Bullitt car. Now if you are saying this is all a fairy tale please explain as this is the first I have heard about it. I find it odd that Kevin would spin a tail that could hurt his credibility in the industry.

There are NO W code mustangs period produced by ford. There was one that was found to be faked a few years ago. I also spoke to Kevin Marti because of an issue with the reproduction ignition wires. I asked him just this question less than eight months ago.  So yes, it's not a unicorn, it's a myth.
